4410/2000 The first number is 4410 pounds the second number is 2000 kilograms
GVWR 7200/3266 means you have a light duty truck. You have 6 lugs on the wheels. The real 3/4 ton trucks are 8700 lbs GVWR and have 8 lugs on the wheels.
Look in the glove box for the RPO codes. They will tell you what rear axle ratio was installed by the factory.

Just a gut felling not knowing all the information I will speculate the truck will handle the tow rating fine but the pin weight(weight on the hitch in the bed) might be over or near the rating....at 20% it would be 1400#s (I used 7,000#s total). Maybe not?....If the vehicle is in good repair, I would use it but that is me..... Others my have a different opinion.

xyzer,
What If I have installed "Helwig" springs or the "Super Springs"? I am looking at having new shocks installed anyways. The Cargo Weight Rating listed inside the glove-box is 1291 LBS.

As I responded in a PM to JB...
... It sounds like you're already using this truck with the trailer. Helper springs and the lot are never going to convert the this truck to HD performance. The rear wheels will be overloaded. The tires will be overloaded. The rear axles will be overloaded. The wheel bearings will be overloaded. Etc ... ad infinitum... The best approach short of changing the truck is to realize its limits. Keep the weight hauled down. Don't take everything you might need, just the basics. Don't take a half cord of firewood for camping. Be sure to keep the trailer load balanced to avoid extra weight on the hitch. Check tire condition and pressure often. Follow the severe duty maintenance schedule.
Keep your speed reasonable. Brake early. Drive defensively.

Hi,
As Hosspuller has stated I'd be more concerned of rear axle rating and tire load. I have an 89 2500 burbie(gvwr-8600. rear axle 5600). We've pulled newer Bison 3horse slant bumper(4,400lbs empty) and it will pull it fine empty and with 1 horse, but add 2nd or 3rdhorse(or more gear) and you will definitely notice added weight(especially hills). Problem is with 5.7 engine(ours has 15,000 on rebuild with stronger forged lower end) that still only makes so much power. Your engine is 2 years newer should be similar to ours w/ Vortec coming out few years later I believe. Have since upgraded to 01 2500hd GMC with 8.1/Allison combo and is night and day difference. Make sure tires are up to snuff and good brake controller(prodigy-?) since older Chevy's are not noted for best brakes.

The springs don't change the 1291 cargo rating. Just make it handle the load better. You are right on the edge of being under trucked IMHO. If it was mine.....hauling localy or short trips longer maybe with one horse I would put a set of good properly rated tires on the truck have it checked out in the brake and rear axle area. If you are new at hauling in a heavy load situation you may want to re-think the combination. If I have to be in max load situation I would prefer a G/N over a B/P.
You would really know your situation if you wieghed the trailer so you knew how much payload it really had. If you could weigh the trailer with someone elses truck you would really know what you are dealing with. You need to know how much weight is being put in the bed of the truck for sure. Quoted trailer weights can be way off target! Either way.
